Determine the class invariants- Ruby

Ruby has many predefined exceptions classes (like ArgumentError) and new ones can be created easily by sub-classing StandardError, so it's easy to raise appropriate exceptions.

We would use assertions frequently when discussing ADTs and data structures and algorithms which implement them and we would put checks in Ruby code to do assertion checking. We would also state pre- and post-conditions and class invariants in comments using below symbols.
